Banc d'essai de vanne papillon à verrouillage horizontal MDV-2000/3.75-S

introduction du produit

The MDV-2000/3.75-S Horizontal Claw-Type Butterfly Valve Test Bench is a pressure testing bench used for butterfly valves and check valves. It is applicable to straight-through flanged or wafer-type butterfly valves within DN1000–DN2000.

Description du produit

MDV-2000/3.75-S integrates the hydraulic system, electrical control system, high/low-pressure water pump pressure supply device, oil pressure / water pressure / gas pressure instrumentation system, control valve system, clamping worktable system, and medium circulation storage tank.

The bench uses a claw-type clamping structure to clamp the valve flange end face. The clamping force is adjustable. The sealing between the butterfly valve and blind plate uses an end-face O-ring sealing method, and the leakage position can be observed.
